LV-Beschreibung

Intendierte Lernergebnisse

This lecture provides some basic knowledges concerning the modeling process of both linear and nonlinear dynamical systems (NDS) in engineering. Both continuous and discrete nonlinear dynamics systems are considered.

Regarding continuous nonlinear dynamical systems, several mathematical models are obtained in forms of ordinary differential equations (ODEs) and/or partial differential equations (PDEs). Each of these equations describes the dynamics of a specific system, scenario, or phenomenon in engineering (Mechanics, Electro-mechanics, Control systems, Electronics, Transportation, Telematics, etc.). For each ODE, the analytical study is considered and several analytical methods are proposed (e.g. Mean/Average method, Harmonic Balance, Multiple time scales, etc.) in order to derive approximate analytical solutions. The stability and bifurcation analysis of ODEs using some well-known classical methods (e.g. Routh-Hurwitz theorem for local stability, and Lyapunov theorem for global stability, Shilnikov theorem for bifurcation and analytic chaos detection) is also considered. Further, several analytical methods for bifurcation analysis and chaos detection in NDS are considered and some specific case studies are investigated for illustration of the concepts. Analytical expressions/formulae are obtained in order to predict the occurrence of a specific type of bifurcation (e.g. Period-doubling, Sudden-transition, Andronov-hopf bifurcation, pitchfork bifurcation, and Hopf-pitchfork bifurcation). 

The lecture presents concepts for the design of electronic circuits for solving stiff ODEs .

Regarding discrete dynamical systems, various mathematical models are considered in form of coupled algebraic equations. For each set of coupled equations, the analytical study is considered and several analytical methods are proposed (e.g. iterative or recursive method, and geometrical method) in order to derive analytical solutions. The stability and bifurcation analysis is conducted using some well-known classical methods (e.g. exponential, and graphical methods).

The Lecture also proposes methods and concepts (e.g. Separation of variables, and Fourier analysis) for solving PDEs analytically. The stability analysis of some classical numerical schemes (e.g. Finite difference method, and method of lines) for solving PDEs is considered.

Overall, the main objectives of this lecture are expressed by the following keywords: Mathematical modeling of NDS using ODEs and PDEs, Analytical solutions of ODEs and PDEs, Design of electronic circuits for solving ODEs and PDEs, Stability analysis of ODEs, Stability of the numerical schemes for solving PDEs, Analytical solutions of DNDS (discrete nonlinear dynamical systems), stability analysis of DNDS, Bifurcation analysis and chaos detection in NDS, Cellular Neural Networks (CNNs) and applications in engineering. The general expectation regarding the knowledge to be provided/acquired is as follows:

  • Mastering of the basic concepts for modeling nonlinear dynamical systems in engineering. These systems are generally expressed in form of ODEs and/or PDEs.
  • Mastering of analytical methods for solving continuous NDS (i.e. ODEs and PDEs).
  • Mastering of analytical methods for solving DNDS (discrete nonlinear dynamical systems) and stability analysis of DNDS.
  • Mastering of analytical methods for stability analysis of NDS modeled by ODEs and PDEs.
  • Mastering of analytical methods for Bifurcation analysis and Chaos detection in NDS modeled by ODEs and PDEs.
  • Mastering of the design of electronic circuits for solving ODEs.
  • Development of a theoretical framework for Cellular Neural Networks (CNNs) and applications in Nonlinear dynamics and Transportation (e.g. Solving ODEs and PDES, Simulation of traffic flow, Supply chain, Image processing).


Lehrmethodik

  • The slides are available for the whole lecture. These slides are uploaded in the MOODLE system. The full content of each slide is systematically explained by the Lecturer. Additional examples which are not included in slides will be proposed by the Lecturer to allow good understanding of the information provided.  
  • The slides contain exercices with solutions for the good understanding of the content of each chapter. These solutions are systematically explained (during the lecture) by the Lecturer.
  • The slides contain exercices without solutions to be solved by students during the lecture (this is part of oral exam). The students are fully assisted by the Lecturer in order to obtain correct/exact solutions to the proposed exercices. This will help to check whether the students have understood the chapters or not.
  •  The slides contain exercices without solutions to be solved as Homework by students. This will help to test the self-learning potential of students.
